There is a 5 year age spread here with the Female being Older which makes things interesting.

She just happen to like her little brother. Plus he is close and very game. Neither is going to tell but I am willing to bet the parents know.

My kids are young adults still living at home, Common in Hawaii, and they have been very close from toddler age. They have never done anything and i would know, but I also would not have cared from about 14 on as long as theykept it private.

Their Mother who is fairly gameherself would absolutly Freak to the point of death. However she would Not Call the Cops or anything.
